The ASCILLA KNX 4-channel pushbutton is a KNX device for loads on/off switching, light fittings dimming, motorised actuators control or other programmable control and command functions. It features a temperature room controller and is designed for wall installation on a round or squared flush mounting box with 60mm distance between fixing holes. Each channel can be programmed separately to perform 1 or 2 bus functions and features four LEDs white and red which can be programmed, for instance, as either feedback status or as orientation nightlight. When you press a rocker key, the device transmits a telegram onto the bus. The telegram is received and executed by one or more KNX actuators, depending on the initial programming. The device is powered by the KNX bus line with 30 Vdc SELV voltage and does not require auxiliary power supply.
